Running a benchmark (e.g. alioth.thread-ring)
script/run alioth.thread-ring 1000
Running a baseline test
Baseline tests execute a java-equivalent benchmark and compare execution times to the respective clojure benchmarks. The specifications for the baseline tests are in https://github.com/clojure/test.benchmark/blob/master/src/baseline/clojure/baseline/spec.clj
# this will pull down the non-CA repo into src/baseline and build mvn compile -Pbaseline # afterwards you can execute baseline tests as follows # default, run all baseline tests 3x, sample and report script/run baseline.exec # run all baseline tests 10x, sample and report script/run baseline.exec 10 # run mandelbrot and thread-ring baseline tests once and report script/run baseline.exec 1 mandelbrot thread-ring
TODO: hook baseline test execution into maven test cycle and generate a jenkins-consumable report
There are a number of completed benchmarks, but there is a lot more left to do. Andy Fingerhut has a suit of benchmarks tailored for Clojure 1.2 and need updated or redone for Clojure 1.3 (https://github.com/jafingerhut/clojure-benchmarks).
A good general approach is to examine the fastest alioth implementations, usually Java or C, and write a Clojure port. Fast small programs in any language are also worthy of examination. These benchmarks should demonstrate how to write idiomatic high-performance Clojure.
Long term goal is a performance regression test suit ...
